Experimental determination of the relationship between NDT parameters and the compressive strength of concrete
Kozáček, Vojtěch ; Komárková, Tereza (referee) ; Kocáb, Dalibor (advisor)
The diploma thesis deals with non-destructive testing of concrete as well as with the relationship between determined parameters and the compressive strength of concrete. The thesis is mainly focused on the ultrasonic pulse velocity method and the rebound hammer test. The experimental part of the thesis describes non-destructive tests performed on concrete blocks. The compressive strength was tested on the drill cores taken from the concrete blocks. The aim of this thesis is to find regression models of the relationship between the compressive strength and non-destructive parameters, and the subsequent analysis of the results.

Survey and Diagnostics of Reinforced Concrete Structure
Richterová, Dominika ; Heřmánková, Věra (referee) ; Anton, Ondřej (advisor)
The main theme of this diploma thesis is a building survey and diagnostics of a reinforced concrete construction. In the first, theoretical part the focus lies on a description of each method for testing constructions and their evaluation. The second, practical part focuses mainly on finding of material characteristics and reinforcement of particular parts of the construction. On basis of obtained information, the final part of this paper focuses on static assessment of chosen parts of the construction.

Diagnosis of the fire damaged bridge
Olejková, Sabina ; Láník, Jaromír (referee) ; Cikrle, Petr (advisor)
This thesis is about assessment of a bridge construction influenced by fire accident. The bridge is situated at the highway D46 beyond the town Držovice. Within this construction research, there will be mentioned diagnostic methods – A non- destructive method (Ultrasonic pulse method and hardness tests) and destructive methods (borehole and tear off tests). For find out in which way was the concrete of the bridge damaged and hurt while facing a high temperature of fire, there were taken samples, which were analyzed by physical and chemical test. We can analyze composition and microstructure of the concrete. The result of this tests will be evaluated, and the actions of a remediation will be suggested.
